We are the same. Went from 12 hrs straight at night to up feeding all night this last 2 nights.15 weeks and I think we've hit the dreaded sleep regression. I'm going on my 5th or 6th night of very little sleep after my boys previously sleeping all night. They are waking up in 15/20 minute spurts all night long I'm exhausted.
I hope we are the same. I was getting used to a full night sleep again!Holefully it doesn't last long for you both. Ours lasted 4 nights and he is back to sleeping through again thankfully.
Is anyone's baby rolling yet?
